[0023] With reference to any one of the first aspect, or the fifth
to the fourteenth possible implementations of the first aspect, in

[0024] With reference to any one of the first aspect, or the fifth
to the fourteenth possible implementations of the first aspect, in

percentages less than or equal to 0.1%.
[0027] With reference to any one of the first aspect, or the fifth
to the eighteenth possible implementations of the first aspect, in
a nineteenth possible implementation, the mass percentage of the
chromium may be any mass percentage less than or equal to 0.2%.
[0028] With reference to any one of the first aspect, or the fifth
to the eighteenth possible implementations of the first aspect, in
a twentieth possible implementation, a range of the mass percentage

less than or equal to 0.2%.
[0029] With reference to any one of the first aspect, or the fifth
to the twentieth possible implementations of the first aspect, in a
twenty-first possible implementation, the mass percentage of the
zirconium may be any mass percentage less than or equal to
0.2%.
[0030] With reference to any one of the first aspect, or the fifth
to the twentieth possible implementations of the first aspect, in a

[0032] With reference to any one of the first aspect, or the fifth
to the twenty-second possible implementations of the first aspect,
in a twenty-fourth possible implementation, a range of the mass
percentage of the ferrum may be a range between any two mass
percentages less than or equal to 0.3%.
[0033] In the embodiments of the aluminum alloy material in the
first aspect, the mass percentage of the zinc and the mass
percentage of the magnesium may enable the zinc and the magnesium
to form a compound MgZn.sub.2. The MgZn.sub.2 may be used as a main
strengthening compound of the aluminum alloy material to improve
mechanical performance (for example, mechanical properties of
materials) of the aluminum alloy material. The improved mechanical
performance includes at least one or more of tensile strength,
yield strength, and hardness.
[0034] The mass percentage of the copper may enable the copper to
combine with the zinc to form CuAl.sub.2. The CuAl.sub.2 can
produce a significant effect in aging strengthening and increase
strength of the aluminum alloy material. In addition, excessive
copper does not lead to reduction in corrosion resistance of the
aluminum alloy material. This helps the aluminum alloy material
form a good appearance through anodizing. In a general case, less
copper helps the aluminum alloy material form a better appearance
through anodizing, and excessive copper makes an anodic oxide film
yellow.
[0035] The mass percentage of the titanium may enable the titanium
and the zinc to form an intermetallic compound TiAl.sub.3. The
intermetallic compound TiAl.sub.3 can effectively refine a grain.
This helps increase the strength of the aluminum alloy
material.
[0036] The mass percentage of the boron may enable the boron, the
titanium, and the zinc to form a compound or an intermediate
compound such as TiB.sub.2, AlB.sub.2, or (Al, Ti)B.sub.2 such that
a quantity of effective nucleation particles is increased, an
effect of refining a grain can be significantly improved, and the
aluminum alloy material can have fine grains with great dimensional
uniformity. This helps increase the strength of the aluminum alloy
material. In addition, because the aluminum alloy material has fine
grains with great dimensional uniformity, a probability that an
obvious speckle appears on the aluminum alloy material after
anodizing can be effectively reduced. This helps obtain an
excellent appearance through anodizing.
[0037] The mass percentage of the silicon may enable the silicon
and the magnesium to form a strengthening phase Mg.sub.2Si to
increase the strength of the aluminum alloy material. In addition,
excessive Si does not affect an appearance of the aluminum alloy
material obtained through anodizing.
[0038] The manganese is an impurity element, and the mass
percentage of the manganese can prevent the manganese, the ferrum,
the silicon, and the zinc from generating excessive impurity
compounds (for example, Al.sub.6(FeMn) and Al(MnFe)Si). The
impurity compound affects the appearance of the aluminum alloy
material obtained through anodizing. For example, a stripe may
appear on the aluminum alloy material after anodizing.
[0039] The chromium is an impurity element, and the mass percentage
of the chromium can prevent excessive chromium of the aluminum
alloy material from increasing quench sensitivity. If the aluminum
alloy material has excessively high quench sensitivity, the anodic
oxide film of the aluminum alloy material becomes yellow after
anodizing. This is unfavorable for the aluminum alloy material to
obtain an excellent appearance through anodizing.
[0040] The zirconium is an impurity element, and the mass
percentage of the zirconium can avoid a case in which excessive
zirconium leads to an unfavorable effect in obtaining an excellent
appearance of the aluminum alloy material through anodizing.
[0041] The ferrum is an impurity element, and the mass percentage
of the ferrum can avoid a case in which excessive ferrum leads to
an unfavorable effect in obtaining an excellent appearance of the
aluminum alloy material through anodizing.
[0042] According to a second aspect, an embodiment of the present
disclosure provides an aluminum alloy material, including zinc
whose mass percentage is from 4.5% to 12%, magnesium whose mass
percentage is from 1.01% to 1.29%, copper whose mass percentage is
less than or equal to 0.6%, titanium whose mass percentage is from
0.001% to 0.5%, manganese whose mass percentage is less than or
equal to 0.1%, chromium whose mass percentage is less than or equal
to 0.2%, zirconium whose mass percentage is less than or equal to
0.2%, silicon whose mass percentage is from 0.001% to 0.3%, ferrum
whose mass percentage is less than or equal to 0.3%, aluminum, and
other inevitable impurities.
[0043] The aluminum alloy material provided in this embodiment of
the second aspect of the present disclosure has high strength, and
can obtain an aesthetic appearance through anodic oxidation
treatment.
[0044] In a first possible implementation of the second aspect, the
mass percentage of the zinc includes from 5.0% to 8.0%, the mass
percentage of the magnesium includes from 1.01% to 1.25%, the mass
percentage of the copper includes less than or equal to 0.01%, the

than or equal to 0.01%, the mass percentage of the silicon includes
from 0.01% to 0.1%, and the mass percentage of the ferrum includes
less than or equal to 0.1%.
[0045] In a second possible implementation of the second aspect,
the mass percentage of the zinc includes from 5.2% to 5.9%, the
mass percentage of the magnesium includes from 1.01% to 1.2%, the
mass percentage of the copper includes from 0.002% to 0.006%, the
mass percentage of the titanium includes from 0.01% to 0.02%, the
mass percentage of the manganese includes from 0.001% to 0.005%,
the mass percentage of the chromium includes from 0.0008% to
0.002%, the mass percentage of the zirconium includes less than or
equal to 0.01%, the mass percentage of the silicon includes from
0.03% to 0.06%, and the mass percentage of the ferrum includes from
0.04% to 0.12%.
[0046] With reference to any one of the second aspect, or the first
to the second possible implementations of the second aspect, in a
third possible implementation, a ratio of the mass percentage of
the zinc to the mass percentage of the magnesium (or a ratio of a
mass fraction of the zinc to a mass fraction of the magnesium or a
ratio of mass of the zinc to mass of the magnesium) includes a
ratio of zinc/magnesium is from 3 to 7.
[0047] When the ratio of the mass percentage of the zinc to the
mass percentage of the magnesium is from 3 to 7, a good appearance
can be obtained after anodizing is performed on the aluminum alloy
material, for example, a delicate metal texture and/or a great
variety of colors (such as silver, gold, and gray) are/is
obtained.
[0048] With reference to the second aspect, in a fourth possible
implementation, the mass percentage of the zinc may be any mass
percentage within a range of 4.5% to 12%.
[0049] With reference to the second aspect, in a fifth possible
implementation, a range of the mass percentage of the zinc may be a
range between any two mass percentages within a range of 4.5% to
12%.
[0050] With reference to any one of the second aspect, or the
fourth to the fifth possible implementations of the second aspect,
in a sixth possible implementation, the mass percentage of the
magnesium may be any mass percentage within a range of 1.01% to
1.29%.

[0066] In the embodiments of the aluminum alloy material in the
second aspect, the mass percentage of the zinc and the mass
percentage of the magnesium may enable the zinc and the magnesium
to form a compound MgZn.sub.2. The MgZn.sub.2 may be used as a main
strengthening compound of the aluminum alloy material, to improve
mechanical performance (for example, mechanical properties of
materials) of the aluminum alloy material. The improved mechanical
performance includes at least one or more of tensile strength,
yield strength, and hardness.
[0067] The mass percentage of the copper may enable the copper to
combine with the zinc to form CuAl.sub.2. The CuAl.sub.2 can
produce a significant effect in aging strengthening and increase
strength of the aluminum alloy material. In addition, excessive
copper does not lead to reduction in corrosion resistance of the
aluminum alloy material. This helps the aluminum alloy material
form a good appearance through anodizing. In a general case, less
copper helps the aluminum alloy material form a better appearance
through anodizing, and excessive copper makes an anodic oxide film
yellow.
[0068] The mass percentage of the titanium may enable the titanium
and the zinc to form an intermetallic compound TiAl.sub.3. The
intermetallic compound TiAl.sub.3 can effectively refine a grain.
This helps increase the strength of the aluminum alloy
material.
[0069] The mass percentage of the silicon may enable the silicon
and the magnesium to form a strengthening phase Mg.sub.2Si to
increase the strength of the aluminum alloy material. In addition,
excessive Si does not affect an appearance of the aluminum alloy
material obtained through anodizing. Further, the silicon helps
refine an alloy grain, increase metal fluidity, and improve alloy
casting performance and a heat treatment strengthening effect,
thereby increasing the strength of the aluminum alloy material.
[0070] The manganese is an impurity element, and the mass
percentage of the manganese can prevent the manganese, the ferrum,
the silicon, and the zinc from generating excessive impurity
compounds (for example, Al.sub.6(FeMn) and Al(MnFe)Si). The
impurity compound affects the appearance of the aluminum alloy
material obtained through anodizing. For example, a stripe may
appear on the aluminum alloy material after anodizing.
[0071] The chromium is an impurity element, and the mass percentage
of the chromium can prevent excessive chromium of the aluminum
alloy material from increasing quench sensitivity. If the aluminum
alloy material has excessively high quench sensitivity, the anodic
oxide film of the aluminum alloy material becomes yellow after
anodizing. This is unfavorable for the aluminum alloy material to
obtain an excellent appearance through anodizing.
[0072] The zirconium is an impurity element, and the mass
percentage of the zirconium can avoid a case in which excessive
zirconium leads to an unfavorable effect in obtaining an excellent
appearance of the aluminum alloy material through anodizing.
[0073] The ferrum is an impurity element, and the mass percentage
of the ferrum can avoid a case in which excessive ferrum leads to
an unfavorable effect in obtaining an excellent appearance of the
aluminum alloy material through anodizing.
[0074] According to a third aspect, an embodiment of the present
disclosure provides an aluminum alloy sheet. The aluminum alloy
sheet is made of an aluminum alloy material, and the aluminum alloy
material includes one or more of the aluminum alloy material in the
first aspect and the aluminum alloy material in the second

disclosure provides an aluminum alloy bar. The aluminum alloy bar
is made of an aluminum alloy material, and the aluminum alloy
material includes one or more of the aluminum alloy material in the
first aspect and the aluminum alloy material in the second
aspect.

disclosure provides a housing. The housing is fastened on an outer
surface of an apparatus, and includes a base, and a fixing part
disposed on the base, the base is approximately plate-shaped or
box-shaped or cap-shaped or frame-shaped, the fixing part is
configured to mount the housing with another component of the
apparatus, the housing is made of an aluminum alloy material, and
the aluminum alloy material includes one or more of the aluminum
alloy material in the first aspect and the aluminum alloy material
in the second aspect.
[0077] The aluminum alloy material in the first aspect and the
aluminum alloy material in the second aspect that are provided in
the embodiments of the present disclosure may be applied to
housings of various apparatuses, to provide strong structural
strength support for the apparatus and increase an anti-bending and
anti-deformation capability of the apparatus. When the apparatus is
subjected to external force, the apparatus is not easily deformed
or bent such that strength of the whole apparatus is increased, and
a bending damage rate of the whole apparatus is reduced.
[0078] In addition, the aluminum alloy material in the first aspect
and the aluminum alloy material in the second aspect that are
provided in the embodiments of the present disclosure have an
excellent anodizing property such that a housing made of the
various aluminum alloy materials can have an aesthetic appearance
through anodizing, and a requirement of a user for a multi-color
multi-texture industrial design (ID) appearance of a housing can be
met. For example, a high-quality metal texture can be provided for
the housing, to improve user experience.

surface of the apparatus to form accommodation space, at least one
component of the component is accommodated in the accommodation
space, at least one part of the housing is made of an aluminum
alloy material, and the aluminum alloy material includes one or
more of the aluminum alloy material in the first aspect and the

aluminum alloy material in the first aspect and the aluminum alloy
material in the second aspect. The housing not only provides better
strength support and protection for the apparatus, but also can
obtain a good appearance through anodizing, to provide a good
decorative effect for the apparatus and improve user
experience.
[0081] With reference to the sixth aspect, in a first possible

[0093] In Table 1, the second, the third or the fourth type of mass
percentage (or mass fraction) of the components of the
Al--Zn--Mg-based high-strength boron-containing aluminum alloy
material is within a range of the first type of mass percentage (or
mass fraction).
[0094] The following describes a function of each component and
various mass percentages (or mass fractions) of each component in
embodiments of different formulations of the boron-containing
aluminum alloy material.
[0095] In terms of the zinc and the magnesium, in the embodiments
of the boron-containing aluminum alloy material, a mass percentage
of the zinc and a mass percentage of the magnesium may enable the
zinc and the magnesium to form a compound MgZn.sub.2. The
MgZn.sub.2 may be used as a main strengthening compound of the
boron-containing aluminum alloy material to improve mechanical
performance (for example, mechanical properties of materials) of
the boron-containing aluminum alloy material. The improved
mechanical performance includes at least one or more of tensile
strength, yield strength, and hardness. In a specific
implementation, a ratio of the mass percentage of the zinc to the
mass percentage of the magnesium (or a ratio of a mass fraction of
the zinc to a mass fraction of the magnesium or a ratio of mass of
the zinc to mass of the magnesium) may include a ratio of
zinc/magnesium is from 3 to 7. When the ratio of the mass
percentage of the zinc to the mass percentage of the magnesium is
from 3 to 7, a good appearance can be obtained after anodizing is
performed on the boron-containing aluminum alloy material, for
example, a delicate metal texture and/or a great variety of colors
(such as silver, gold, and gray) are/is obtained. In a specific
implementation, the mass percentage of the zinc may be any mass
percentage within a range of 4.5% to 12.0%, and a range of the mass
percentage of the zinc may be a range between any two mass
percentages within a range of 4.5% to 12.0%. In a specific
implementation, the mass percentage of the magnesium may be any
mass percentage within a range of 0.7% to 3.0%, and a range of the
mass percentage of the magnesium may be a range between any two
mass percentages within a range of 0.7% to 3.0%.
[0096] In terms of the copper, in the embodiments of the
boron-containing aluminum alloy material, a mass percentage of the
copper may enable the copper to combine with the zinc to form
CuAl.sub.2. The CuAl.sub.2 can produce a significant effect in
aging strengthening and increase strength of the boron-containing
aluminum alloy material. In addition, excessive copper does not
lead to reduction in corrosion resistance of the boron-containing
aluminum alloy material. This helps the boron-containing aluminum
alloy material form a good appearance through anodizing. In a
general case, less copper helps the boron-containing aluminum alloy
material form a better appearance through anodizing, and excessive
copper makes an anodic oxide film yellow. In a specific
implementation, the mass percentage of the copper may be any mass
percentage less than or equal to 0.6%, and a range of the mass
percentage of the copper may be a range between any two mass
percentages less than or equal to 0.6%.
[0097] In terms of the titanium, in the embodiments of the
boron-containing aluminum alloy material, a mass percentage of the
titanium may enable the titanium and the zinc to form an
intermetallic compound TiAl.sub.3. The intermetallic compound
TiAl.sub.3 can effectively refine a grain. This helps increase the
strength of the boron-containing aluminum alloy material. In a
specific implementation, the mass percentage of the titanium may be
any mass percentage within a range of 0.001% to 0.5%, and a range
of the mass percentage of the titanium may be a range between any
two mass percentages within a range of 0.001% to 0.5%.
[0098] In terms of the boron, in the embodiments of the
boron-containing aluminum alloy material, a mass percentage of the
boron may enable the boron, the titanium, and the zinc to form a
compound or an intermediate compound such as TiB.sub.2, A1B.sub.2,
or (A1,Ti)B.sub.2 such that a quantity of effective nucleation
particles is increased, an effect of refining a grain can be
significantly improved, and the boron-containing aluminum alloy
material can have fine grains with great dimensional uniformity.
This helps increase the strength of the boron-containing aluminum
alloy material. In addition, because the boron-containing aluminum
alloy material has fine grains with great dimensional uniformity, a
probability that an obvious speckle appears on the boron-containing
aluminum alloy material after anodizing can be effectively reduced.
This helps obtain an excellent appearance through anodizing. In a
specific implementation, the mass percentage of the boron may be
any mass percentage within a range of 0.00011% to 0.2%, and a range
of the mass percentage of the boron may be a range between any two
mass percentages within a range of 0.00011% to 0.2%.
[0099] In terms of the silicon, in the embodiments of the
boron-containing aluminum alloy material, a mass percentage of the
silicon may enable the silicon and the magnesium to form a
strengthening phase Mg.sub.2Si, to increase the strength of the
boron-containing aluminum alloy material. In addition, excessive Si
does not affect an appearance of the boron-containing aluminum
alloy material obtained through anodizing. In a specific
implementation, the mass percentage of the silicon may be any mass
percentage less than or equal to 0.3%, and a range of the mass
percentage of the silicon may be a range between any two mass
percentages less than or equal to 0.3%.
[0100] In terms of the manganese, in the embodiments of the
boron-containing aluminum alloy material, the manganese is an
impurity element, and a mass percentage of the manganese can
prevent the manganese, the ferrum, the silicon, and the zinc from
generating excessive impurity compounds (for example,
Al.sub.6(FeMn) and Al(MnFe)Si). The impurity compound affects the
appearance of the boron-containing aluminum alloy material obtained
through anodizing. For example, a stripe may appear on the
boron-containing aluminum alloy material after anodizing. In a
specific implementation, the mass percentage of the manganese may
be any mass percentage less than or equal to 0.1%, and a range of
the mass percentage of the manganese may be a range between any two
mass percentages less than or equal to 0.1%.
[0101] In terms of the chromium, in the embodiments of the
boron-containing aluminum alloy material, the chromium is an
impurity element, and a mass percentage of the chromium can prevent
excessive chromium of the boron-containing aluminum alloy material
from increasing quench sensitivity. If the boron-containing
aluminum alloy material has excessively high quench sensitivity,
the anodic oxide film of the boron-containing aluminum alloy
material becomes yellow after anodizing. This is unfavorable for
the boron-containing aluminum alloy material to obtain an excellent
appearance through anodizing. In a specific implementation, the
mass percentage of the chromium may be any mass percentage less
than or equal to 0.2%, and a range of the mass percentage of the
chromium may be a range between any two mass percentages less than
or equal to 0.2%.
[0102] In terms of the zirconium, in the embodiments of the
boron-containing aluminum alloy material, the zirconium is an
impurity element, and a mass percentage of the zirconium can avoid
a case in which excessive zirconium leads to an unfavorable effect
in obtaining an excellent appearance of the boron-containing
aluminum alloy material through anodizing. In a specific
implementation, the mass percentage of the zirconium may be any
mass percentage less than or equal to 0.2%, and a range of the mass
percentage of the zirconium may be a range between any two mass
percentages less than or equal to 0.2%.
[0103] In terms of the ferrum, in the embodiments of the
boron-containing aluminum alloy material, the ferrum is an impurity
element, and a mass percentage of the ferrum can avoid a case in
which excessive ferrum leads to an unfavorable effect in obtaining
an excellent appearance of the boron-containing aluminum alloy
material through anodizing. In a specific implementation, the mass
percentage of the ferrum may be any mass percentage less than or
equal to 0.3%, and a range of the mass percentage of the ferrum may
be a range between any two mass percentages less than or equal to
0.3%.
[0104] In view of the above, as an Al--Zn--Mg-based
boron-containing aluminum alloy material, the boron-containing
aluminum alloy material provided in the embodiments of present
disclosure has high strength and can obtain an aesthetic appearance
through anodic oxidation treatment.
